In Situ Integrated Titanium Oxide Synaptic Phototransistor Enabling Multimodal Plasticity and Noise‐Robust Selective Attention

Advanced Materials Technologies, EarlyView.
An in situ integrated TiO2/SiOx/Al2O3 synaptic phototransistor couples ultraviolet and electrical stimuli within a scalable, CMOS‐compatible oxide stack. Multimodal plasticity, spike‐timing‐dependent learning, and bee‐inspired associative conditioning are achieved through trap‐mediated temporal dynamics.

Causal‐Guided Ultra‐Long‐Term Time Series Forecasting Via Anticipated Covariates

Advanced Science, EarlyView.
Often treated as unknown, information from the future remains underutilized.We demonstrate that in a coupled dynamical system, providing the future state of the effect enables accurate forecasting of the cause for a long timesteps. A time series forecasting paradigm that introduces anticipated covariates to represent such known future states is ...

Computation‐Guided Tunnel Engineering Enhances O2 Transport and H2O2 Resistance of Fe(II)/α‐Ketoglutarate‐Dependent Dioxygenases

Advanced Science, EarlyView.
This study presents a computational tunnel engineering strategy in Fe(II)/α‐ketoglutarate‐dependent dioxygenases (αKGDs) to enhance oxygen (O2) transport, an essential molecule for αKGDs, and limit hydrogen peroxide (H2O2) entry, an inhibitor from the αKG supply system.

Fair multi-party concurrent signature scheme

Tongxin xuebao, 2014
Multi-party concurrent signatures were first proposed by Tonien et al at ISC2006,but Xie and Tan pointed Tonien et al's scheme doesn't satisfy fairness and they reconstructed multi-party concurrent signature schemes respectively.Through analysis,the ...

Hierarchical Physical‐Cyber Encryption via Metasurface‐Encoded Holographic Keys

Advanced Science, EarlyView.
ABSTRACT Physical‐layer encryption based on metasurfaces has emerged as a promising alternative to conventional algorithmic cryptography by embedding security into physical processes. However, most existing metasurface‐based encryption schemes operate within single‐stage or static frameworks, where correct physical illumination directly reveals the ...

Heterogeneous Secure Multi-Party Computation [PDF]

, 2012
The increased processing power and storage capacity of in-home and mobile computing devices has motivated their inclusion in distributed and cloud computing systems. The resulting diverse environment creates a strong requirement for secure computations, which can be realised by Secure Multi-Party Computation (MPC).

YAP1‐Driven Pathogenic Fibro‐Adipogenic Progenitors Secrete IL‐6 and FGF21 to Mediate Muscle‐Bone Crosstalk and Promote Bone Loss

Advanced Science, EarlyView.
Fibro‐adipogenic progenitors (FAPs) in atrophic muscle undergo YAP1‐driven pathogenic activation, secreting IL‐6 and FGF21 as bone‐catabolic myokines that mediate muscle‐bone crosstalk and promote bone loss. Genetic or pharmacological targeting of this YAP1‐FAP‐myokine axis rescues skeletal deterioration, identifying FAP‐derived myokines as therapeutic
